Display Directories with a Bold Font – How to enable? with .bash_profile?
提问by Ross
I'm using a linux server that display directories in a bold font, and files in a normal font.
我使用的 linux 服务器以粗体显示目录，并以普通字体显示文件。
e.g. $ lsproduces
例如$ ls产生
afile.txt afolderanotherfile.txt anotherfolder
afile.txt afolderanotherfile.txt anotherfolder
I'd like to use this feature on some other servers. How can it be done? with the .bash_profile?
我想在其他一些服务器上使用此功能。怎么做到呢？与.bash_profile？
If anyone has other ideas on how to differentiate folders from file, they'd be good to know?
如果有人对如何区分文件夹和文件有其他想法，他们会很高兴知道吗？

You need to give lsthe --colors=…option (e.g. via an alias). To actually configure the LS_COLORSenvironmental variable used to define the colours, one good way is to create a configuration file for dircolors, e.g. with just bold (attribute 1) directories:
你需要给ls的--colors=…选项（例如，通过一个别名）。要实际配置LS_COLORS用于定义颜色的环境变量，一种好方法是为dircolors，例如仅使用粗体（属性 1）目录创建配置文件：
echo DIR 1 >~/.dir_colors
Then in your .bash_profileor .bashrc, evalthe output of dircolorsrun on that file to set LS_COLORSaccording to your configuration. The relevant lines in my .bashrc(copied from somewhere) look like this:
然后在您的.bash_profileor 中.bashrc，根据您的配置在该文件eval上dircolors运行的输出进行设置LS_COLORS。我.bashrc（从某处复制）中的相关行如下所示：
if [ -n "$COLORTERM" ]; then
alias ls='ls -F --color=auto'
if [ -x "`which dircolors`" -a -r "$HOME/.dir_colors" ]; then
eval `dircolors -b "$HOME/.dir_colors"`
fi
else
alias ls='ls -F'
fi
Note that some terminals do not, by default, display the bold attribute as true bold but rather just use a brighter colour. You need to configure your terminal to get real bold.
请注意，某些终端默认情况下不会将粗体属性显示为真正的粗体，而是仅使用更亮的颜色。您需要配置您的终端以获得真正的大胆。
See the dircolors --print-databasefor an example of a “complete” configuration file.
有关dircolors --print-database“完整”配置文件的示例，请参见。

add this to your .bashrc or .profile: alias ls='ls --color=auto'
将此添加到您的 .bashrc 或 .profile： alias ls='ls --color=auto'

lsdoes have the ability to differentiate items using the -Fflag.
ls确实有能力使用-F标志区分项目。
From the man page:
从手册页：
-F, --classify
append indicator (one of */=>@|) to entries
All you have to do is add -Fto your lscommand in your terminal like so:
您所要做的就是在终端中添加-F到您的ls命令中，如下所示：
$ ls -F
You can make this permanent by setting up an alias by opening your .bashrc(or similar) file and adding:
您可以通过打开您的.bashrc（或类似的）文件并添加以下内容来设置别名，从而使其永久化：
alias ls='ls -F'
alias ls='ls -F'
After setting that (and either logging out and back on or running source ~/.bashrc), you can simply run lsand it will always assume you added -F.
设置后（以及注销并重新启动或运行source ~/.bashrc），您可以简单地运行ls，它会始终假设您添加了-F.

It's done with an environment variable. Start with reading the ls man page:
它是通过环境变量完成的。首先阅读 ls 手册页：
$ man ls
You may not be able to get just bold, but only bold with a specific color.
您可能无法仅使用粗体，而只能使用特定颜色进行粗体。
